Recently, I made a mistake regarding the Fast and Furious "gun walking" program. I claimed It was started by Bush. That particular gun walking program was indeed begun by President Obama but it was a continuation of George Bush's 2006 gun walking program called "Operation Wide Receiver".
So, gun walking was begun by the ATF under Bush while Obama unwisely restarted the program with his own version. Both have been highly criticized and rightly so.
